Electrolux Dryer Error Code 0x72

Error code 0x72 indicates a Heater NTC Error, specifically a fault with the NTC2 temperature sensor in the heater circuit. The control board has detected that the NTC2 sensor signal is outside its expected range, so it has disabled heating as a safety precaution. The fault can originate from the sensor itself, the wiring harness, or the main control board.

A reset may temporarily clear the fault code, but if the underlying cause, whether a failed NTC2 sensor, wiring defect, or board issue, has not been resolved, the code will return once the dryer attempts to heat again. Resetting without diagnosis is not a lasting fix and could delay identifying a component that needs to be replaced.

Repair costs vary depending on which component has failed. Replacing an NTC2 sensor is generally the least expensive fix, with parts typically ranging from $15 to $50 and a modest labor charge if a technician is hired. Wiring repairs fall in a similar range. Main control board replacement is the most costly scenario, with parts alone often ranging from $100 to $250 or more, plus labor.

Some steps are accessible to a confident DIYer. You can inspect the J8 connector for corrosion, check for visibly damaged wiring, and use a multimeter to measure resistance across the J8-1 and J8-2 terminals, looking for a reading near 5.2 KΩ. If the sensor or wiring is found to be faulty, replacing those components is a moderate-difficulty repair. Main board replacement is more involved and is best handled by a technician if other diagnostics do not resolve the issue.

You should not operate the dryer normally while this fault is present. The 0x72 error causes the control board to disable the heater, so the dryer will not dry clothes effectively anyway. More importantly, running the appliance with an undiagnosed temperature sensor fault removes a key safety safeguard against overheating. The faulty component should be identified and repaired before resuming normal use.
